TreeVersity

Comparing Trees is difficult. To address this, we present TreeVersity a new interactive visualization that gives users powerful tools to detect both node value changes and topological differences. TreeVersity uses dual comparison techniques (side-by-side and explicit differences) and tabular representations, to facilitate the understanding and navigation of the differences. TreeVersity’s design employs carefully designed color palettes to show positive/negative, absolute, and relative value changes; shapes that preattentively show these changes; and novel graphical approaches that highlight created and removed nodes’.
